942,864. Knitting. COTTON, SILK AND MAN MADE FIBRES RESEARCH ASSOCIATION. Oct. 5,1960 [Oct. 7, 1959], No. 33929/59. Headings D1C and D1K. In a warp knitting machine using bearded or tongue (e.g. F. N. F.) needles, yarn ends passing from the supply to the last course knitted are guided on the opposite side of the needles from the fabric longitudinally of the needle bed to the position corresponding to the desired lay of the threads at the fabric side, Fig. 16, and then at right angles to the needle bed Fig. 1c, Fig. 1cc , the needles, having been retracted during this movement, are moved into position for engagement with the yarn ends which are again guided longitudinally, Fig. 1d, and then at right angles to the needle bed Fig. 1f, Fig. 1ff to engage the needle hook after which the needles are operated to draw the loops through those of the previous course, Fig. 1g, Fig. 1gg. In knitting an 0-1/2-1 fabric the guide bar carrying guides G1. G2, G3- - is displaced one needle space to the right, Fig. 1a the needles (having stems S1, S2 - - and beards B1, B2- -) being below the sinker block, and sinkers SK1,Sk2, - - - are withdrawn into their block, Fig.1c. The needles rise and the guide bar moves two spaces to the left and a comb C engages the yarn ends which engage the needle beards until the needles rise sufficiently for them to engage the stems, Fig. 1f and 1ff, the guides and comb C having risen with the needles. The needles fall and the yarns slide behind the beards which are then closed by a presser P, comb C being withdrawn, and the yarn is drawn through the previous loop L<2>. Guides G1, G2 - are lowered meanwhile for the start of the next cycle when the guides move to the left. A crossed loop fabric 1-0/1-2 may be knitted by this method, the guides being moved one space to the right before operating the sinkers and then one space to the right again before operating the comb C, Figs. 2d and 3c. In a modification, using an additional comb C<1> a crossed-loop fabric can be knitted with the supply yarn lying below the other leg. The yarn guides are moved along two spaces the sinkers SK are operated and the guides move back when the comb C<1> is operated, Fig. 3e. The guides then move two spaces to the right and comb C is operated so that the yarn extending between the combs C and C<1> is engaged behind the needle beard, Figs. 3h and 3hh, the comb C<1> engaging in a groove in presser P. The stitch is completed in the normal way. By modifying the guide bar movement, loops with double crossing, Fig. 7, may be formed. Needles S are clamped in needle bed 12 which is reciprocated vertically by two or more push rods 15 each connected by a rod 14 to an eccentric 13 on main shaft 10. Guide bars 20, 21 carrying guides G are reciprocated vertically through push rods 18 and connecting rods 17 by eccentrics 16 on shaft 10. A pinion 73 on shaft 10 drives a pin drum 90 through pinions and spur wheels. Followers 94, 95 at the lower and upper ends respectively of pivoted rocker levers 92, 93 are biased by springs 96 to engage face cams 76, 78 and guide bars 20, 21 to produce a two course endwise movement cycle of bars 20, 21, these cams performing one revolution to each two revolutions of shaft. Cams 60 on shaft 10 operate levers 61 are connected to lifters 62 carrying caps 64 which support a rod 63 extending across the machine having a slot to receive sinker butts and hence to impart arcuate reciprocating movement to the sinkers SK. Presser plate P is connected by a lever 35 to a lever 34 having a roller follower 37 biased into engagement with the face of cam 33 on shaft 10. The individual members of comb C are carried on a plate 25 attached to lever 24 mounted with lever 23 on common shafts 26, 28, lever 23 having a follower 29 biased into engagement with a cam 22 on shaft 10 to reciprocate comb C horizontally. Vertical movement of comb C is caused by a lever 106 pinned to shaft 28 and engaged by a roller 105 carried on a push rod 104 which is actuated by a pivoted lever 101 carrying a roller 103 which engages a cam 100 on shaft 10. Levers 106 and 103 are spring biased against roller 105 and cam 100 respectively. Front comb C<1> consists of a series of flat blades slidable in slots in a fixed bar 117 above drum 90. Pins 119 in holes in bar 117 are biased downwardly by springs 120 to urge combs C<1> into engagement with pins 87 in the drum 90. The outer ends of combs C<1> engage grooves in bars 48, 49 fixed to the ends of levers 47 which are raised and lowered through rods 44 and rockers 42 by cams 41. The shaft 86 of drum 90 is turned to bring successive rows of pins into operation by a rack wheel 84 turned by a pawl 85 on lever 83 which engages edge cam 29. Combs C<1> are reciprocated horizontally passing between the needles during part of the motion by cams 52 at either end of shaft 10 acting through push rods 53, levers 54 and links 55 to impart angular movement to lever 47. Specification 888, 701 is referred to.
